GAUGE AND SUPPORT FOR BARS.

Application filed November 4, 1925. Serial No. 66,750.

My invention relates to supporting and spacing devices for concrete reinforcing elements, and has particularly to dowith devices for use in connection with the con 6 struction of concrete roadways.

An essential element ofthe devices illustrated herein is a supporting member having a foot or base adapted to rest on the soil, the upper end being in abutting engagement 10 with a bar or bar supporting element. The

supporting member is arranged in cooperative relation to a stake or prong adapted to enter the soil, the body of the supporting member is bowed or curved inwardly into engagement with a portion of the stake or pin. By reason of this arrangement, an extremely firm frictional engagement is secured between the cooperating parts, such engagement being necessary in order to prevent accidental separation of the parts in handling and shipping.

As a further important element, I'provide in connection with the stake, a lateral arm having the double function ofv spacing the device'from the side form and of enclosing and retaining the bar in its correct position.

The device will be more readily under stood by reference to the accompanying drawings, in which;

Fig. 1 is a sectional view through a portion of a roadway in which my improved device has been incorporated;

Fig. 2 is a plan view thereof before the concrete is poured; a

Fig. 3 is an enlarged perspective View of my improved device;

larly to'Figs. 1 to 3, inclusive, it will be seen that I provide a supporting member having a foot, 10, inwardly curved body 11, andan upper end, 12, terminating in a right angle extension, 13, having an open side notch, 14, therein. The parts, 10, 12, of the member are parallel and are apertured to accommodate the prong, 15, of a round wire spacing element, the lowerend of which is adapted to enter the ground as shown in Fig. 1. The upper end, 16, of the stake is bent to a right angle and the arm acts as a spacer or gauge to determine the location of the bar, 17, relzitive to the side form,18. The right angle bend in the wire stake provides for the driving of the stake into the ground if the soil is hard, the blow being applied at the angle. It will be noted that the arm, 15, is in register with the notch, 14:, and, due to the round cross section of the prong or stake, it may be rotated in the apertures in the supporting member; in other words, it may be swung intothe dotted line position of Fig. 2 to permit of insertion of the bar, 17. Thereafter it is returned to the full line position and the bar is securely confined within the seat provided at the upper .end'of the support.

the superimposed weight and this insures an accurate gauge'for the vertical position of the bar while the lateral arm, 16, insures accurate lateral positioning.

In the modification shown in Fig. 1, all of the parts heretofore described are identi- I have, however, provided for the support of a second reinforcing rod, 19, in vertical alignment'wi-th This is accomplished by pro vicling a, supp emental supp ting member In the construction of Fig. 5, the stake,

is unchanged and the supporting element is similar, comprising a foot, 24, a bowed body, 25, an upper end, 26, the terminal portion 27,01? which extends upwardly, then laterally and downwardly to form second bar seat, 28. The terminal portion, 29, of this seat is likewise notched to receive the lateral arm, 16, of the stake. This construction provides "for the support of two reinforcing bars in horizontal alignment.

In the construction of Figs. 7 and 8, a stake 30 is utilized having an eye, '31 in its upper end for supporting a bar, 32. At an intermediate point in the length of the stake, I provide an offset 33, acting as a stop for the supporting member of depth gauge. This member has a foot, 34 a bowed body,

- portion, 35, and'a lateral upper end, 36, the

parts, 34, 36, being apertured to accommodate the stake. The same principle is employed as heretofore described and the parts are firmly held by frictional engagement.

In the construction of Figs. 9 and 10, the stake 37 is straight throughout its body portion, having an eye 38 in its upper end for supporting a bar, 39. The depth gauge is the same as that heretofore described, ex-

cept that it is of" greater height, the abutment being between the upper end, 40 of the gauge and the eye. The same foot, 41, and

bowed body, 42, are utilized with the described advantages.

Obviously the construction 1s capable of other modifications than those shown and I do not wish to be limited except as indicated in the appended claims:

1. In. a device of the class described, the combination of a stake and a stop member, said stop member having a bowed body and laterally projecting apertured ends adapted to receive said stake, the bowed body being in contact with said stake.

2. In. a device of the class described, the combination of a round stake adapted to be driven into the soil and a stop member for limiting the entrance of the stake into the soil, said stop member having a body and.

.a'pertured ends for the reception of said stake, the body portion being inwardly deflected between its ends and in contact with said stake.

3. In a device of the class described, the

combination of a round stake adapted to bar seat.

and apertured ends for the reception of said stake, and a horizontally disposed arm secured to saidstake at its upper end and acting as a lateral spacer.

4. In a device of the class described, the combination of a round stake adapted to be driven into thesoil and a stop member for.

limiting the entrance of the stake into the soil, said stop member having a body and apertured ends for the reception of said stake,'the upper end of said stop member providing a seat for a reinforcing bar.

5. In a device of the class described, the combination of a 'round stake adapted to be driven into the soil and a stop member for limiting the entrance of the stake into the soil, said stop member having a body and apertured ends for the reception of said stake, and a horizontally disposed arm se cured to said stake at its upper end and acting as a lateral spacer, the upper lateral extension on said spacing member providing a seat for a reinforcing bar. v p

6. In a device of the class described, the combination of a roundstake adapted to be driven into the soil and a stop member for limiting the entrance of the stake into the soil, said stop member having a body and apertured ends for the reception of said stake, a horizontally disposed arm secured to said 'stalre at its upper end and acting as a lateral spacer, the upper lateral extension on said spacing member providing a seat for a reinforcing bar, the spacing element of the stake being movable relative to the stop member in order to open andclose the seat tnred to receive the stake, the bowed portion being in contact with the stake, the/angular extension of the stake lying over the 8. In combination a stake having a ver tical prong and a horizontal extension, a stop member having a bowed body and angularends, the lower end portion acting as a foot and. the upper end portion being depressed to form a bar seat, the angular extension being apertured to accommodate the prongs and said horizontal portion of, the stake overlying the bar seat, the terminal portion of the bar seat being supported on the horizontal portion of thestake.
